Method for removing impurities in liquid metal |
摘要 |
A method and an apparatus for removing hydrogen and other impurities contained in liquid metal. The liquid metal containing hydrogen and other impurities is cooled below their saturation temperature to precipitate hydrogen and other impurities in the form of various compounds of the metal, and the precipitate is trapped and accumulated. The thus accumulated precipitate is then dissolved in a small amount of liquid metal having a temperature at least above said saturation temperature to produce high temperature liquid metal having a high hydrogen concentration. The high temperature liquid metal is contacted with one side of a metal membrane having a hydrogen permeability, another side of which being at reduced pressure, thereby selectively removing hydrogen in gaseous state from the liquid metal.
